Solution Overview
Problem
The existing installation methods for photovoltaic modules are complex, labor-intensive, and pose safety risks due to the need for on-site assembly and handling of heavy modules, which also results in aesthetic and structural integration issues.
Innovation Solution
A pre-assembled modular structure with a support base comprising two parallel sections connected by traverses, allowing for easy transportation and quick installation, featuring a quick hooking system for photovoltaic laminates that integrates seamlessly with building structures, reducing installation complexity and risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If photovoltaic modules are assembled directly on houses and industries using support frames and shear connections, then the modules can be fixed to the covering, but the assembly and installation operation becomes long and complex
Solution Approach 1:
The support base is pre-assembled in a factory setting with all necessary components (support legs, cross members, fastening elements) prepared beforehand. This preliminary assembly eliminates the need for complex on-site construction, reducing installation time and complexity while maintaining reliable module fixation capability
Solution Approach 2:
Multiple components (support legs, cross members, fastening elements) are merged into a single integrated support base assembly. This consolidation reduces the number of separate operations needed during installation, transforming a complex multi-step process into a simpler single-unit installation
2Reliability
If photovoltaic modules are assembled directly on houses and industries, then the modules can be installed on the covering, but human efforts and installation time are significantly increased
Solution Approach 1:
The support base is pre-assembled in a factory setting with all necessary components (support legs, cross members, fastening elements) prepared beforehand. This preliminary assembly eliminates the need for complex on-site construction, reducing installation time and complexity while maintaining reliable module fixation capability
Solution Approach 2:
The photovoltaic system is divided into modular components: pre-assembled support bases and separate photovoltaic modules. This segmentation allows the support structure to be manufactured efficiently in a controlled factory environment and then quickly deployed on-site, significantly improving installation productivity
3Reliability
If photovoltaic modules are handled and positioned manually during installation, then the modules can be fixed to the support frame, but workers face psycho-physical stress and safety risks due to working in altitude and handling heavy modules
Solution Approach 1:
The support base is pre-assembled in a factory setting with all necessary components (support legs, cross members, fastening elements) prepared beforehand. This preliminary assembly eliminates the need for complex on-site construction, reducing installation time and complexity while maintaining reliable module fixation capability
Solution Approach 2:
The pre-assembled support base acts as an intermediary that receives the photovoltaic modules in a controlled manner. The base provides pre-positioned mounting points and structural support, allowing modules to be attached more safely with reduced manual handling and positioning requirements
4Reliability
If traditional support frames and shear connections are used for module installation, then modules can be fixed to the covering, but the aesthetic factor is not always appreciated and integration with building structure is poor
Solution Approach 1:
The support base integrates multiple functions into a single structure: structural support, module mounting, and aesthetic integration with the building covering. This merging eliminates the visual clutter of separate support frames and connections, achieving both reliable support and improved aesthetic appearance
Solution Approach 2:
The support base is designed as a multi-functional component that simultaneously provides structural support, module attachment capability, and aesthetic integration with the building envelope. This universal design replaces multiple separate elements with a single component that fulfills all necessary functions

AI summary
The present invention concerns a modular type assembly system comprising: - A photovoltaic laminate (110); - A support base comprising a first section (2), a second section (3) and two traverses (21) that join transversally the first section to the second section in such a way as to form a support plan on which the photovoltaic laminate (110) results arranged; - Hooking profiles (25) to fix the photovoltaic laminate (110) in a removable manner to the support base in such a way as to form a single modular element transportable in situ for the installation. It is also included a fixing bracket kit 4 to connect the module to the structure 100 and to allow to draw near a module to the subsequent one.
